docker-ops SKILL.md skillA
This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.
docker-ops from nordz0r/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nordz0r/skills/docker-ops@git:20261015.e46a793Pins git:20261015.e46a793 in mdr.lock. Pin the fingerprint instead.

Hands-on Docker Engine and Docker Compose v2: Dockerfile, multi-stage, healthcheck, networks, volumes, bind mounts, logs, registry, docker compose up/down/config, BuildKit, non-root USER, restart policy. Use for any container task on a host: build an image, write compose.yaml, fix Restarting, read docker logs, docker inspect, overlay2, docker.sock, prune, CI image build. Triggers: docker, dockerfile, docker compose, compose.yaml, container, image build, docker logs, healthcheck, bind mount…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Docker Ops Skill for Docker Engine and Compose v2 on a Linux host. Hand over ready `Dockerfile`/`compose.yaml` files and verification commands, not generic advice. Do not use it as the primary skill for Kubernetes, GitLab YAML or the Ansible `community.docker` module — those are `gitlab-ci` and `ansible-playbook`. Handle GitLab `docker:dind` together with `gitlab-ci`. ## When to use - Write or fix a Dockerfile / compose.yaml. - Container is `Restarting`, unhealthy, cannot resolve DNS, cannot see a volume. - Image build, tags, push to a registry. - Networks, ports, bind mounts, named volumes, tmpfs. - Logs, `inspect`, `events`, disk used by overlay2. ## Workflow 1. Confirm the runtime: `docker version`, `docker compose version`. Compose v2 is `docker compose`, not `docker-compose`. 2. If there is a compose file, run `docker compose config` and `ps -a` first. 3. Take symptoms from the container: `ps`, `logs --tail`, `inspect`, `health`. 4. Change code/config declaratively in the Dockerfile/compose; `docker exec` is not a permanent fix. 5. Verify: container healthy, port listening, volume in place, no `latest` tag in prod. ## Rules …

How to install
mdr add nordz0r/skills/docker-ops@sha256:f7613517d53fbdccThe line at the top of this page pins the label git:20261015.e46a793, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
